1. 1. Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage

   Uppsats för yrkesexamina på avancerad nivå, KTH/Transportvetenskap

   Författare :Ylva Almqvist; [2011]
   Nyckelord :dual tires; super single tire; ATB VÄG 2005; DCSE; permanent deformation; fatigue cracking; BWIM.;

   Sammanfattning : When designing roads it’s important to know what loads will be driven on it. The axles on heavy vehicles can either have super single tires or dual tires which, according to studies, damage the roads differently. LÄS MER

3. 2. Implementation of the SuperPave IDT analysis procedure

   Master-uppsats, KTH/Väg- och banteknik

   Författare :Guangli Du; [2010]
   Nyckelord :SuperPave indirect tensile test; resilient modulus; creep compliance; fracture energy; dissipated creep strain energy;

   Sammanfattning : Cracking is one of the most severe distress modes of asphaltpavements. Thus characterising the fracture resistance properties of asphaltmixtures is the key issue for improving the performance relatedmixture design. LÄS MER

4. 3. Towards a Uniform Fracture Mechanics-Based Framework for Flexible Pavement Design

   Master-uppsats, KTH/Väg- och banteknik

   Författare :Prabir Das; [2009]
   Nyckelord :Crack growth; Low temperature cracking; Fracture mechanics; Dissipated creep strain energy; Asphalt pavements; Energy Ratio;

   Sammanfattning : Cracking is an important potential failure mechanism for pavement structures. By combining a strain energy-based fracture criterion with conventional fracture mechanics based on the Energy Ratio (ER) concept, crack growth in asphalt can be investigated, and a low temperature Thermal Cracking model (TCMODEL) can be introduced.
